I suggest to make some changes in button panel in WebUI.
1) First of all hide "Debug" button into "More actions..." or in Settings window at all.
2) "Add URL" button change to "Add URL/torrent" (or name it simply "Add" or "Open"). This button opens dialog window, where we can add "URL of a .torrent file or a magnet/oneswarm URI" or open torrent-file from computer.
3) Remove "Play" button. Everybody uses double-click to play media :)
4) Add "Start/Stop" button to start or stop downloading/uploading selected items.
5) Move "Manage visibility" button from "More actions..." menu and name it "Visibility".
6) Move "View swarm details" button from "More actions..." and name it "Details".
See my screenshot: http://img94.imageshack.us/img94/3492/newpanel.png (sorry for missed css-styles)
P.S. For example, I'm tired to open select menu "More actions..." to start/stop swarm every time...
